EhrView and the Application Toolkit
EhrView is a generic component enabling viewing of any EHR data held in an EhrBank repository with a normal web browser.
All openEHR EHR information can be viewed in a generic fashion, requiring no programming. Presentation specific to content can be implemented via the EhrView plug-in XSLT mechanism, allowing developers to customise display according to clinical requirements.
EhrView provides the following functions:
- EhrBank login, via EhrGate running on the server.
- A view of all Compositions, including previous versions, in a given clinical subject’s EHR.
- Filtering of Compositions in an EHR by date, user, topic, archetype, etc.
- Viewing information in different contexts such as information about a diagnosis in a summary list or showing all related information.
- Ability to display the results of queries.
EhrView greatly simplifies the display of information from a subject's EHR and allows control of presentation due to a strong grip on the meaning of the information in the EHR. This is done by linking display logic to particular archetypes and user categories, and means that information can be presented in a manner most appropriate to the current user.
It is also possible to record the viewing of EHR data for audit purposes and to ensure accountability to patients and maintainance of their privacy.
